武漢太陽(yáng)減壓閥組RPGC-LAN-CBB/S減壓閥是通過(guò)調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過(guò)改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。調(diào)壓步驟

1、關(guān)閉減壓閥前的閘閥，開(kāi)啟減壓閥后的閘閥，制造下游低壓環(huán)境；

2、將調(diào)節(jié)螺釘

按逆時(shí)針旋轉(zhuǎn)至上位置（相對(duì)低出口壓力），然后關(guān)閉減壓閥后閘閥；

3、慢慢開(kāi)啟減壓閥前的閘閥至全開(kāi)；

4、順時(shí)針慢慢旋轉(zhuǎn)調(diào)節(jié)螺釘，將出口壓力調(diào)至所需要的壓力（以閥后表壓為準(zhǔn)）；調(diào)整好后，將鎖緊

螺母鎖緊，打開(kāi)減壓閥后閘閥；

5、如在調(diào)整時(shí)出口壓力高于設(shè)定壓力，須從一步開(kāi)始重新調(diào)整，即只能從低壓向高壓調(diào)
